Flatiron District in the context of "Empire State Building"

Chelsea is a neighborhood on the West Side of the borough of Manhattan in New York City. The area's boundaries are roughly 14th Street to the south, the Hudson River and West Street to the west, and Sixth Avenue to the east, with its northern boundary variously described as near the upper 20sor 34th Street, the next major crosstown street to the north. To the northwest of Chelsea is the neighborhood of Hell's Kitchen, as well as Hudson Yards; to the northeast are the Garment District and the remainder of Midtown South; to the east are NoMad and the Flatiron District; to the southwest is the Meatpacking District; and to the south and southeast are the West Village and the remainder of Greenwich Village. Chelsea was named after an estate in the area which, in turn, was named after the Royal Hospital Chelsea in London which, in its turn, was named after the Chelsea District of London (England).

Chelsea contains the Chelsea Historic District and its extension, which were designated by the New York City Landmarks Preservation Commission in 1970 and 1981 respectively. The district was added to the National Register of Historic Places in 1977, and expanded in 1982 to include contiguous blocks containing particularly significant examples of period architecture.

Madison Square is a public square formed by the intersection of Fifth Avenue and Broadway at 23rd Street in the New York City borough of Manhattan. The square was named for Founding Father James Madison, the fourth president of the United States. The focus of the square is Madison Square Park, a 6.2-acre (2.5-hectare) public park, which is bounded on the east by Madison Avenue (which starts at the park's southeast corner at 23rd Street); on the south by 23rd Street; on the north by 26th Street; and on the west by Fifth Avenue and Broadway as they cross.

The park and the square are at the northern (uptown) end of the Flatiron District neighborhood of Manhattan. The neighborhood to the north and west of the park is NoMad ("NOrth of MADison Square Park") and to the north and east is Rose Hill.

Silicon Alley is an area of high tech companies centered around southern Manhattan's Flatiron district in New York City. The term was coined in the 1990s during the dot-com boom, alluding to California's Silicon Valley tech center. The term has grown somewhat obsolete since 2003 as New York tech companies spread outside of Manhattan, and New York as a whole is now a top-tier global high technology hub. Silicon Alley, once a metonym for the sphere encompassing the metropolitan region's high technology industries, is no longer a relevant moniker as the city's tech environment has expanded dramatically both in location and in its scope. New York City's current tech sphere encompasses a universal array of applications involving artificial intelligence, the internet, new media, financial technology (fintech) and cryptocurrency, biotechnology, game design, and other fields within information technology that are supported by its entrepreneurship ecosystem and venture capital investments.

Sixth Avenue, also known as Avenue of the Americas, is a major thoroughfare in the New York City borough of Manhattan. The avenue is commercial for much of its length, and traffic runs northbound, or uptown.

Sixth Avenue begins four blocks below Canal Street, at Franklin Street in Tribeca, where the northbound Church Street divides into Sixth Avenue to the left and the local continuation of Church Street to the right, which then ends at Canal Street. From this beginning, Sixth Avenue traverses SoHo and Greenwich Village, roughly divides Chelsea from the Flatiron District and NoMad, passes through the Garment District and skirts the edge of the Theater District while passing through Midtown Manhattan. Although it is officially named "Avenue of the Americas", this name is seldom used by New Yorkers.

14th Street is a major crosstown street in the New York City borough of Manhattan, traveling between Eleventh Avenue on Manhattan's West Side and Avenue C on Manhattan's East Side. It forms a boundary between several neighborhoods and is sometimes considered the border between Lower Manhattan and Midtown Manhattan.

At Broadway, 14th Street forms the southern boundary of Union Square. It is also considered the southern boundary of Chelsea, Flatiron/Lower Midtown, and Gramercy, and the northern boundary of Greenwich Village, Alphabet City, and the East Village. West of Third Avenue, 14th Street marks the southern terminus of western Manhattan's grid system. North of 14th Street, the streets make up a near-perfect grid that runs in numerical order. South of 14th, the grid continues in the East Village almost perfectly, except in Greenwich Village, where an older and less uniform grid plan applies.

The Flatiron Building, originally the Fuller Building, is a 22-story, 285-foot-tall (86.9 m) steel-framed triangular building at 175 Fifth Avenue in the Flatiron District neighborhood of Manhattan in New York City. Designed by Daniel Burnham and Frederick P. Dinkelberg, and sometimes called, in its early days, "Burnham's Folly", it was opened in 1902. The building sits on a triangular block formed by Fifth Avenue, Broadway, and East 22nd Street—where the building's 87-foot (27 m) back end is located—with East 23rd Street grazing the triangle's northern (uptown) peak. The name "Flatiron" derives from its triangular shape, which recalls that of a cast-iron clothes iron.

The Flatiron Building was developed as the headquarters of construction firm Fuller Company, which acquired the site from the Newhouse family in May 1901. Construction proceeded rapidly, and the building opened on October 1, 1902. Though the building was originally 20 floors, a "cowcatcher" retail space (a low attached building so called for its resemblance to the device on rail locomotives) and penthouse were added shortly after the building's opening. The Fuller Company sold the building in 1925 to an investment syndicate. The Equitable Life Assurance Society took over the building after a foreclosure auction in 1933 and sold it to another syndicate in 1945. Helmsley-Spear managed the building for much of the late 20th century, renovating it several times. The Newmark Group started managing the building in 1997. Ownership was divided among several companies, which started renovating the building again in 2019. Jacob Garlick agreed to acquire the Flatiron Building at an auction in early 2023, but failed to pay the required deposit, and three of the four existing ownership groups took over the building. In October 2023, the building's owners announced that it would be converted to residential condominiums; the project is planned to be complete by 2026.

Rose Hill is a neighborhood in the New York City borough of Manhattan, between the neighborhoods of Murray Hill to the north and Gramercy Park to the south, Kips Bay to the east, the Flatiron District to the southwest, and NoMad to the northwest. The formerly unnamed area is sometimes considered to be a part of NoMad, because the name "Rose Hill" was chiefly used for the area in the 18th and 19th centuries, and is not very commonly used to refer to the area in the 2010s.
